We preview a theatrical production that opens next Wednesday at Carthage College in the studio theater: "Dear Elizabeth" by Sarah Ruhl. We speak with three Carthage seniors: Annaliese Ruhs, who is the director - and Jessie Skonesey and Chase Juster, who comprise the two-person cast. The play is based on letters that were exchanged between two gifted 20th century poets - Elizabeth Bishop and Robert Lowell - over the course of thirty years.
